Involvering i gruppearbeid
2023
Forskningsarbeidets formål er å undersøke hvordan elever arbeider i grupper med utforsking- og problemløsningsoppgaver. Gruppearbeid som undervisningsform stiller flere sosiale krav til deltakerne, som for eksempel å kunne lytte, stille spørsmål, korrigere og kritisere hverandre underveis, noe som er krevende for flere elever (Simensen, 2022; Sjöblom & Meaney, 2021). Til grunn for forskningsdesignet og analysen lå Louis Radfords sosialkulturelle teori om objektivisering (Radford, 2021). I teorien er involvering i felles arbeid («joint labor») en betingelse for tilgang og utvikling av matematisk kompetanse for eleven. Involvering er derfor et utgangspunkt i forskningsspørsmålene som stilles:…
Unveiling species assemblage rules in gypsum plant communities
2023
Plant communities are not merely snapshots of species located in the same area. Instead, they are dynamic entities connected through complex biotic interactions. Understanding the interplay of processes that bind species within a community is vital for comprehending species maintenance and may assist us in predicting how communities respond to the perturbations of a changing world. This Ph.D. aims to unveil how abiotic conditions, plant strategies, and biotic interactions shape plant communities growing in stressful environments. Plant species can thrive in stressful environments through contrasted strategies, either showing species-specific adaptive strategies or reliance on facilitative i…
La historia de la educación a través de las revistas especializadas: temáticas, producción científica y bibliometría (1961-2022)
2023
Durante las tres últimas décadas se ha producido un importante aumento en cuanto al número de investigaciones en el campo de la Historia de la Educación. Esto, a pesar de favorecer la internacionalización y creación de redes transnacionales de investigación, también aumenta la complejidad de la comprensión global de la disciplina.

Se ha analizado la evolución de la producción a lo largo de los años, citaciones, autores y colaboraciones, países de afiliación, instituciones y colaboraciones…
Meeting the 24-h movement guidelines and health-related outcomes among youth with autism spectrum disorder: a seven-country observational study
2023
Abstract Background Meeting daily guidelines for physical activity, screen time, and sleep duration is associated with a host of health indicators for youth. In this cross-sectional observational study, we investigated the associations between adherence to the movement guidelines and health-related outcomes among youth with autism spectrum disorder (ASD). Methods Parents of youth with ASD (10–17 years) from seven countries and regions were invited to provide online proxy-reports for child’s movement behaviors (i.e., physical activity, sleep and screen time), and health-related outcomes (i.e., body mass index [BMI], general health, and quality of life). A series of multiple linear regression…
A difesa della democrazia. Pensiero politico e visione storica in Sheldon Wolin
2023
A Sheldon Sanford Wolin (1922-2015) va riconosciuto il merito di aver posto la comprensione della democrazia contemporanea lungo le direttrici di un’analisi elaborata per metterne in risalto i principali snodi critici. Gli eventi politici americani remoti e recenti sono da lui ripresi come il sottofondo alla cui luce giudicare le caratteristiche assunte via via dal potere e dal consenso popolare, soprattutto nella versione elitaria che contraddistingue sempre più marcatamente l’esperienza democratica degli ultimi decenni, ravvisandovi il progressivo indebolimento della partecipazione e dello stesso concetto costitutivo di cittadinanza.
Bivalve mollusks shells valorisation and recycling: market potentiality and novel building products
2023
Construction is a fundamental driver of the world economy, recognized as a sector that generates a great contribution to the social and economic development. At the same time, it shows an enormous environmental impact through an unstoppable consumption of non-renewable resources, a high energy consumption, and an associated atmospheric emission of pollutant. Consequently, the research and development of novel and green production processes and sustainable building materials is of paramount importance. The sustainability of materials and production processes could be improved by enhancing and reusing wastes from various industrial sectors. In this paper, the fishery sector will be analysed, …

New Materialist Explorations into Language Education
2023
This open access book analyzes language education through a socio-material framework. The authors revisit their position as researchers by decentering themselves and humans in general from the main focus of research activities and giving way to the materialities that are agentive but often overlooked parts of our research contexts and processes. Through this critical posthumanist realism, they are able to engage in research that sees society as an ethical interrelationship between humans and the material world and explore the socio-materialities of language education from the perspectives of material agency, spatial and embodied materiality, and human and non-human assemblages. Each chapter…
An approach to map nitrous oxide emission risk by soils at regional scale based on soil properties
2023
For "Most" People
2023
This thesis is a rhetorical discourse analysis of FrP and party leader Sylvi Listhaug’s use of right-wing populist discursive strategies and rhetorical tools in Facebook posts between 08.05.21-08.05.23. This approach is used to understand how they are using populist discursive strategies on social media and to which degree social media as a platform can enable populist rhetoric and function to influence and manipulate the masses. The theoretical approach to populism in this thesis bases itself in the discursive approaches of Laclau and Wodak and emphasises how the homogenising effects of empty and floating signifiers appear in the discursive strategies characteristic of right-wing populists…
Profiling the risk of hepatocellular carcinoma after long-term HCV eradication in patients with liver cirrhosis in the PITER cohort
2023
Background and aims: Severe liver disease markers assessed before HCV eradication are acknowledged to usually improve after the SVR. We prospectively evaluated, in the PITER cohort, the long-term HCC risk profile based on predictors monitored after HCV eradication by direct-acting antivirals in patients with cirrhosis. Methods: HCC occurrence was evaluated by Kaplan-Meier analysis. Cox regression analysis identified the post-treatment variables associated with de-novo HCC; their predictive power was presented in a nomogram. Results: After the end of therapy (median follow-up:28.47 months), among 2064 SVR patients, 119 (5.8%) developed de-novo HCC. The HCC incidence was 1.90%, 4.21%, 6.47% a…

From Herder to Strecker: Birth and Developments of the Anthropological Notion of Culture in Germany
2023
Austrian and German anthropological traditions are considered in view of the influence they had on global anthropology. The chapter is built around the centrality of the anthropological notion of culture and cultural dynamics. The particularistic and relativist notion of culture is in fact believed to have emerged from Germany from the eighteenth century, where intellectuals have juxtaposed the term Kultur to Zivilisation. Within German anthropology, universalistic perspectives on culture have continued through the nineteenth century, as in the evolutionary approach of Gustav Klemm and Johann Jakob Bachofen. A different form of cultural universalism was introduced by Adolf Bastian with his …
Investeringsanalyse av anleggsmaskin med grønt hydrogen som energibærer for reduksjon av CO2-utslipp.
2023
For å nå målene i tråd med Parisavtalen er dekarbonisering gjennom å ta i bruk ny teknologi i bygg- og anleggsbransjen en avgjørende faktor. Regjeringen publiserte den 3. juni 2020 en hydrogenstrategi som et bidrag til arbeidet med å utvikle lavutslippsteknologi, hvor bygg- og anleggsbransjen var ekskludert. I denne oppgaven vil vi dermed kartlegge hvordan grønt hydrogen, som en energibærer gjennom brenselcelleteknologi, kan benyttes til å fase ut bruken av fossilt brensel, og dermed redusere klimafotavtrykket til bygg- og anleggsbransjen i tråd med Parisavtalen og FN`s bærekraftsmål. Målet med masteroppgaven er å utarbeide en investeringsanalyse for å danne et beslutningsgrunnlag for hvilk…

Multispecies coinfections and presence of antibiotics shape resistance and fitness costs in a pathogenic bacterium
2023
Increasing antimicrobial resistance (AMR) poses a challenge for treatment of bacterial diseases. In real life, bacterial infections are typically embedded within complex multispecies communities and influenced by the environment, which can shape costs and benefits of AMR. However, knowledge of such interactions and their implications for AMR in vivo is limited. To address this knowledge gap, we investigated fitness-related traits of a pathogenic bacterium (Flavobacterium columnare) in its fish host, capturing the effects of bacterial antibiotic resistance, coinfections between bacterial strains and metazoan parasites (fluke Diplostomum pseudospathaceum) and antibiotic exposure. We quantifie…
Highly-parallelized simulation of a pixelated LArTPC on a GPU
2023
The rapid development of general-purpose computing on graphics processing units (GPGPU) is allowing the implementation of highly-parallelized Monte Carlo simulation chains for particle physics experiments. This technique is particularly suitable for the simulation of a pixelated charge readout for time projection chambers, given the large number of channels that this technology employs. Here we present the first implementation of a full microphysical simulator of a liquid argon time projection chamber (LArTPC) equipped with light readout and pixelated charge readout, developed for the DUNE Near Detector. The software is implemented with an end-to-end set of GPU-optimized algorithms. The alg…
Mekanismene bak den gunstige effekten av trening ved subacromialt smertesyndrom: en sonderende litteraturgjennomgang

Iodination of antipyrine with [N–I–N]+ and carbonyl hypoiodite iodine(i) complexes
2023
A series of iodine(I) complexes, both known and new, were synthesised and the dependence of iodination reactivity on the identity of the Lewis bases and anions present was investigated. Using a previously established screening protocol based on the iodination of antipyrine to iodo-antipyrine, the capability of the iodine(I) species to perform the iodination was tested and compared, especially in relation to Barluenga's reagent, [I(pyridine)2]BF4. The results indicated that the identity of both the Lewis bases and the anion influence the iodination capability of the iodine(I) species, and that the less efficient reagents can deliver favourably comparable percentage conversions with longer re…

The participation of Non-State Actors in the UNESCO Cultural Diversity Convention: Current Status and Proposals for Reform
2023
The paper is articulated into four sections. The first section illustrates the CPPDCE’s legal framework for engagement with actors other than States. It shows that this framework expresses a ''functionalist'' emphasis on NSAs’ capacity of contrib-uting to the adoption of higher quality decisions on the part of States and facilitating their implementation. The second section investigates the relationship between NSAs and the Convention’s bodies. It argues that the existing ''functionalist-oriented'' regula-tion not only has prevented basic stakeholders from having access to the Convention’s processes, but has also created imbalances among participants, to the detriment of the Convention’s ve…

El objetivo de esta tecnología es mejorar la recuperación del material particulado afluente de las ARM mediante la implementación de una unidad de filtración por membrana como paso previo al tratamiento biológico secundario, reduciendo así las necesidades energéticas asociadas a la oxidación aeróbica de la materia orgánica en los sistemas de fangos activos. Asimismo, el fango concentrado en el tanque de membranas puede emplearse para incrementar la producción de metano durante el proceso de digestión anaero…
Economising failure and assembling a failure regime
2023
Sociologists have largely neglected the topic of failure, and particularly the economising of failure, notwithstanding notable exceptions. This is puzzling, given the many adjacent literatures that have addressed the practices and processes of economising. Four features define our approach. First, it is argued that failure has none of the objectivity or inevitability often attributed to it. Second, it is suggested that failure be viewed as a variable ontology object. Third, attention is directed to the calculative infrastructures that operationalise the ideas of failing and failure, and enable them to be acted upon. Fourth, emphasis is placed on the importance of distinguishing between fail…
